Webb Telescope Captures Incredible Distant Space Objects
In the technology era, space telescopes are being developed strong enough to examine far into space without being restricted by the blurry effects of Earth’s atmosphere.
But in a few cases, more than these advanced telescopes are needed to see the galaxies so far away that looking at them is like going back to the beginning of the universe.
Therefore, Astronomers use gravitational lensing to see even far-away space objects. It occurs when an object, such as a galaxy cluster or galaxy, has enough mass to bend space-time so that it behaves as a magnifying glass and brightens the most far away space objects behind it.
By utilizing the above phenomenon, the James Webb Space Telescope witnesses thousands of incredibly distant objects by observing an area known as Pandora’s Cluster or Abell 2744.
Webb telescope uses a mega galaxy cluster composed of three galaxy clusters that contain so much mass that it enables scientists to view regions of space that have never been seen before.
When the first image of the Pandora region came, it was full of foreground clusters and distant galaxies.
This detailed image was captured using Webb’s NIRCam sensor with 30 hours of observation time. Then for further studies, researchers will choose galaxies of their interest and observe them more closely with Webb’s NIRSpec instrument.
